解决方案

  1. 95% 成功率 
    Set a secret key from environment:
app.config['SECRET_KEY'] = os.environ['SECRET_KEY']
  2. 85% 成功率 
    For tests only, generate a fixed key:
app.config['SECRET_KEY'] = 'test-key'

常见但无效的做法:

  1. 90% 失败

    Permanence affects cookie lifetime, not the required signing key.

  2. 70% 失败

    Most session backends still need a secret key for signing.
